    i made this diagram showing how this would work on a 3.0l 2jz, HKS 272 cams(not to scale obviously), looking for 1200bhp
    just wondering if the pipe diameters work and also if doing 3-1 to 2-1 instead of just 6-1 would effect it at all?

    this wasnt what i originally planned on doing because the extra plumbing, turbulence, and cost, but it seems like the only way is to use two if i wanna get alot flow

    any thoughts? thanks

    Depending on how much pressure you want out of the high pressure turbo (the small turbo) you might not really need two 60mm gates. Too large of wastegates blow down the drive pressure quickly when the valve first cracks open.

    You're primary runner and secondary runner diameters don't seem too crazy either. I'd rock it and see what happens! I used to run 2.25" PRIMARIES on my old 3000GT VR4.
